AUGER Filed March 22, 1937 rum jd ATTORNEYS Patented Feb. 8, 1938 ilm'llalz STATES 'PATENT OFFICE-- 'I'he invention relates to an auger and more especially to a post hole auger.

The primary object of the invention is the provision of an auger of this character, wherein power is transmitted thereto from any sultablesource for the operation of the auger and the latter is susceptible of being guided to the work for the formation in the soll of post holes or the like, the auger in its entirety being of novel construction. l0 Another object of the invention is the provision' of an auger of this character, wherein a gear housing or casing constitutes a head which can be suspended from a hanger and also is tted with a handle bar enabling convenient placement and guiding thereof to and from the wor or during operation. s

A further object of the invention is the provision of an auger of this character, which is extremely simple inconstruction, thoroughly reliable 'and effective in operation, readily portable, strong, durable, and inexpensive to manufacture.

With these and. other objects in view, the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter fully described, illustrated in the accompanying drawing, which discloses the preferred embodiment of the invention and pointed out inthe claim hereunto appended.

In the accompanying drawing:

Figure 1 is a side elevation partly in section of an auger constructed in accordance with the invention.

Figure 2 is an elevation thereof.

Figure 3 is'an enlarged sectional viewtaken on the line.3-3 of Figure 2 looking in the-direction of the arrows.

'Figure 4 is a' fragmentary side elevation of a modification. Similar reference characters indicate corresponding parts throughout the several views in the drawing.

Referring to the drawing in detail, Ilv designates a gear housing having a removable top plate II while at the bottom and one side are bearingbosses I2 and I3, respectively, the plate being removably tted and held in place by fasteners I4. Connned within the housing Il is the gear and pinion I5 and I0, respectively; The gear Ii is xed to an auger shaft I1 carrying near its lower end a disk-like cutter Il, the same being peripherally notchedv at dlametrically opposite sides thereof at I! and through these notches extemithe curved cutter blades 2l, these being u reverselyangledtoeachotherandeachisformed slight modication wherein the cutter Adisk I3 .has one blade 34 formed with a saw tooth cuttingv with the cutting edge 2| and pointv22. respectively.

I'he blades are riveted or otherwise made fast at 2l to the disk-like cutter I8 and adapted for the cutting of earth on the driving of the shaft 5 I1 for the formation of a hole in the ground. The cutter I8 at its center is formed with a hub 2l keyed or otherwise made xedvat 25 to theshaft I1 for removability of such cutter when required. 0

. 1 The pinion I6 has its stem or stud axle 28 `joui-nalen in the bearing boss la while the share n is journaled in the boss I2 and this stud axle has fitted thereto a universal joint 21 which is in association with a slip joint including male and fe- 15 male members 28 and'29, respectively, telescopically -interlltted with each other. 'I'he male member 28 has joined with it a universal joint 30, whichvis coupled with a power shaft, a portion thereof being indicated at 3|, from any suitable source of power. The universal joints 21 and 30, respectively, are connected in place. by cotter pins 32 for separable fastening thereof. i.

In Figure 4 of the drawing there is shown a edge 35, this being for relieving rock obstructions in the soil or ground during the operation of the auger.

The top plate II at its center is formed with 30 an upstanding lug 36 having passed transversely therethrough a handle bar 31 constituting a pivot for a bail I8 which is adaptedtc be engaged with the hook 39 of a suspension element, a. portion being indicated at III, so that Vthe auger can 35 be raised or lowered with respect to the work or extracted from a hole after the boring thereof.

The shaft I1 is carriedupwardly through the gear I6 in the housing I0 and has its upper end journaled in the top plate I I, being understood, of 40 course, that sintable anti-friction bearings may be associated with the said shaft as well as with the stud axle 2l.

The 'shaft AI1 at the lower end thereof has formed therein a suitable transverse slot for ac- '45 commodating a blade 4I disposed beneath the disk-like cutter II. This blade 4I is `outwardly tapered and is held secure by rivets or other fas` tenere 42, the purpose of the blade 4I being to clean out. the l'center ofthe hole when the auger '60 is in operation for the boring of such holeandin this manner the dirt will be directed laterally in the path ofthe cutting blades 20.

`. What is claimed is:

An auger of the characterdesmbed comprising u movable top cover, gear and pinion Within the housing and meshing with each other, an auger shaft journaled in the housing and fixed to said gear, an auger cutter carried by said shaft, slip and universal joint connections with the pinion a gear housing forming a head having a reand adapted for driving connection with a source of power, a center lug rising from the said cover, a handle bar engaged in the lug, and a hoist bail straddling the lug and pivoted to the handle bar.
